To all whom it mag concern:

Be it knowm'that I, "GUsTAVUsEEJ-TAFT, of Wliitinsville, in the countyof Worcester. and State of'Massachusettsfh'ave invented certain newanduseful Improvements "in Spinning Frames and I hereby "declare t-hat thefol 1o'wing is-ai full; clear, an d"exact" description of the same,reference being had to .the accom pahyingdrawings;makinga part of. th isspecification.

This -invention" relates to' improvements in, spinning frarnes namely,.for changing the speed of" th-ering-rail *to eft'ectthe laying of? yarnaccordin'g to its size or number on "the? bobbins.

It is desirable to grade the speed of "the ring-rail. For (some coarseyarns one rise and fall of the ring-rail is wanted for thirty revo;lutions of the front roller, and for'finenyarns one rise and fall of thering-rail fortwo hun died and fifty revolutions "of the frontroller. Thespeed of the ring-rail will be varied between these two extremes to suitthe number of the yarn and .its lay upon the bobbin.

The most common way in use to give motion to the heart-shaft is to driveit from the front roll by means of a worm on the front roll of aspinning-frame operating a wormwheel on a vertical or diagonal shaft,near the lower end of which is mounted a bevel-pinion, which drives abevel-gear secured to the heart-shaft. The objections to this method arethat worms and worm-wheels are liable to wear rapidly, and worm-wheelsand bevel-gears are not so convenient for changing speeds as spur-gears,and the former especially requires more fre- I quent oiling.

The object of my invention is to change the speed of the heart-shaft bymeans of interchangeable square-faced spur-gears, and to connect saidspur-gear bya chain and sprocket or chain wheels with the front roll ofa spinning-frame or someintermediate gearing, from which power istaken,and to vary the laying of the yarn on the bobbins; and this Iaccomplish by mounting the interchangeable spurgears upon a studof anarm pivoted to the heart-cam shaft, and covering the heart-cam and itsgears with a bonnet, serving also as a support for the chain-wheel stud.Thus a chain and chain-wheels .anfd spur-wheels are used, and are wellsuited'for that,purpos,e,..not onlyby means of the facility with whichthe change-of speed is made in thejgeaiting, but

the motion. given to theheart-camyanlii through it "to the ring-rail, ismore even-anihsteady, :and avoids the jerkingmotion so common in 'wormand worm-wheelswheretheworhtobe done or the resistanceofleredism'otsteiqyor uniform.

My invention consists in combining witha r-spinning-frame, its heart-camshaft or fistiid, iandheart-shaft spur-gear, an arm pivoted on .-saidshaft, and carrying interchangeable square-faced spur-gears,chain-wheels. and a :chain, through which motion is :tnansn'iittedithereto, as will be' hereinafter described, and pointe'cl out in theclaims.

In the drawings, Figure 1 representsanJend elevation of aspinning-frame"having inyji nprovements. Fig. 2 represents a top view orplan of the same. Fig. 3 represents a side elevation of the same. Fig. 4represents an'enlarged front view and vertical section of the changeablegear, its axle, and carrying-arm. Fig. 5 represents a perspective viewof the gearing shield and support.

The construction and operation of my invention are as follows:

A represents the frame. B B are intermediate gears, through which thefront rolls are driven in common geared spinning-frames. To the hub ofthe gear B, or any other convenient gear, I attach a small sprocket orchain wheel,

0, which is connected to and drives, by means. of the chain 0, a largersprocket-wheel, D,

' ings.

The small change-gear g may have only fifteen teeth, and another, g, mayhave sixty teeth and upward.

Though two gears are shown, one in full and the other in dotted lines,Fig. 4, on the stud upon which they revolve, only one will be used at atime.

The shaft d (carrying the sprocket wheel and pinion f) is supported by ascrew-threaded sleeve, 01, secured to the semi-cylindrical castmetalshield G by a nut, h. The sleeve passing through a slot in the side ofthe shield, its position is thus rendered adjustable.

The shield is secured at one end to the frame of the machine under thebracket-bearing A of the spindle-drivin g cylinder, and at the otherend, at a, in such a position as to cover the heart-cam E, its gear E,the changegears, and their movable support, the arm 1. This arm I ispivoted at one end to the heart-cam shaft or stud e, and controlled atthe other end by a nut, 0', upon a bolt, 1', projecting from one side ofthe arm and passing through a slot, o in the frame. From the oppositeside of the arm I, and adjoining 1', projects a stud, 7:, carrying thechange-gears g or g, and also the pinion I, that meshes with thegear-wheel E on the cam-shaft. This pinion I has its hub projecting farenough to go through the hub of any of the change-gears, as shown inFig. 4, and is keyed thereto.

To make the change and substitute one of the change-gears for the other,a wrench is placed upon the flattened head k of the stud 7c and turned,the nut n being held from turning by the ribs forming the recess in thearm I. The gear g, or any other changegear that may happen to be on, isremoved, and the desired substitute is placed upon the hub of the pinionl, and the stud replaced in its position, the arm I being secured in asuitable position by the nut 1', according to the size of changegear.

Having now fully described my invention, I claim- 1. In combination withthe frame of a spinning-machine, its heart-cam shaft, and heartshaftspur-gear, a lever pivoted on said shaft or stud, and carrying aspur-gear adapted, as described, to be interchangeable with a gear ofdifferent size, substantially as and for the purpose described.

2. The combination, with the frame of a spinning-machine and itsdraw-rollers, of the shield G, attached to said frame, a sleeve andshaft carried by said shield, sprocket-wheels, and chain, as described,and intermediate gears between the draw-rollers and said sleeve andshaft to transmit motion through a pinion and interchangeable gear, asdescribed, to gearwheel E and heart-cam E, substantially as and for thepurpose described.

3. In combination with the heart-cam shaft and gear-wheel E, the arm I,pivoted at one end to heart-cam shaft, the stud Ir, projecting from theside of said arm, the pinion l, and the gear upon said stud, adapted tobe interchangeable, substautially as and for the purpose described.

4. In combination with the frame of a spinning-machine, the heart-camshaft, heart-cam, and its gearing E, the arm I, carrying a pinion andgear adapted to be interchanged, as described, and the shield Gr,attached to the frame, and carrying a stud for a sprocketwheel,substantially as and for the purpose described.
